That's kind of strange because I beat Braccus with four characters on level 10 - one of them a knight, one ranger/fighter and two mages - and I needed more than 3 rounds for them. I think at least 6 or 7...
And I only played on medium difficulty. My level 10 knight had a 70-170 two-handed weapon. But of course my knight only had level 2 way of the warrior and one of my mages was specialized in fire which isn't very useful against Braccus...
I agree that the difficulty still needs some balancing. But some fights are just easier than other fights, espeically if you have a higher level than your opponent. Braccus is level 7 or 8 IIRC which is three levels below yourself at level 10. You have a great party to crack him (melee+water+air). So yes, the fight is easy. But other players maybe don't do each and every quest before encountering him in and are for example only at level 7 with on fire mage in the party. Then the fight is a lot harder...
